What is the composition of JP-8 fuel?
Gasoline and kerosene
At room temperature, how many times longer will it take water to settle out of JP-8 than out of gasoline?
Four
Jet aircraft operating at moderately high altitudes increase the fuel system’s susceptibility to an icing condition, further aggravated by the
higher viscosity of jet fuels
The main fuel control allows the jet engine to safely accelerate, reducing the possibility of
flameout
During a visual inspection, how can you tell when a fuel filter is clogged?
A differential pressure indicator is actuated
On a dual-spool, axial-flow engine, what controls thrust production of the engine?
Controlling turbine inlet temperature
During jet engine deceleration, a hydro mechanical fuel control schedules fuel flow as a function of
burner pressure
what type of fuel control uses items such as thermocouples, relays, amplifiers, and solenoids to help control a jet engine?
Electrohydromechanical
Which term describes a jet engine fuel metering device that is really two fuel controls in one component?
Unified
The F100 UFC senses certain variables from the engine through the use of
a closed loop design
If the safety seals on a fuel system component are broken or removed, and you suspect the factory adjustment was altered, you should
forward the component to the authorized depot fro reflow and resealing
Calibration and/or adjustment screws that require setting during an engine trim procedure must be
safety sealed and/or lockwired
When in the primary mode, what controls the operation of the F100-PW-200 engine?
DEEC
On an F100-PW-220 engine, the DEEC is cooled by
fuel
For actuation of the variable van systems on an F100-PW-220 engine, the MFC provides both the CIVV and
rear compressor variable van actuators with fuel pressure
